More ternary op failures

[mkaput]

The following tests are failing even after #115. I won't have time to investigate them further.

    test "ellipsis does not continue across semicolon-separated // forms" do
      assert Spitfire.parse("x...\n;//y") == s2q("x...\n;//y")
      assert Spitfire.parse("x...\n;\n//y") == s2q("x...\n;\n//y")
      assert Spitfire.parse("x...\n;\n# comment\n//y") == s2q("x...\n;\n# comment\n//y")
    end

    test "parenthesized //(do-end) keeps following when outside slash rhs" do
      assert Spitfire.parse("//(foo do :ok end) when x") == s2q("//(foo do :ok end) when x")
      assert Spitfire.parse("//(foo do :ok end)\nwhen x") == s2q("//(foo do :ok end)\nwhen x")
    end

    test "parenthesized //(do-end) keeps following <- outside slash rhs" do
      assert Spitfire.parse("//(foo do :ok end) <- x") == s2q("//(foo do :ok end) <- x")
      assert Spitfire.parse("//(foo do :ok end)\n<- x") == s2q("//(foo do :ok end)\n<- x")
    end

    test "parenthesized //(do-end) keeps following :: outside slash rhs" do
      assert Spitfire.parse("//(foo do :ok end) :: x") == s2q("//(foo do :ok end) :: x")
      assert Spitfire.parse("//(foo do :ok end)\n:: x") == s2q("//(foo do :ok end)\n:: x")
    end
